Etymology. This epithet is taken from the Latin adjective niger meaning dark-coloured and refers to the species’ overall dark colouration.

Remarks. The dark colour, distinctive rounded shape and puncturation of the pronotum and elytra, and absence of flight wings will quickly serve to determine this species.
